Abstract

A liquid hard surface cleaning composition comprising melamine foam fibers and a formaldehyde scavenger. The liquid hard surface cleaning composition comprises melamine foam fibers that comprise less than about 100 ppm of formaldehyde in solution after 7 days of storage at 50° C. A process of cleaning a hard surface using a liquid hard surface cleaning composition that comprises melamine foam fibers and a formaldehyde scavenger. The use of a formaldehyde scavenger in a liquid hard surface cleaning composition comprising melamine foam fibers, to provide a liquid hard surface cleaning composition showing no or low levels of formaldehyde generation upon storage of the composition over prolonged periods of time.
